. ,CULTIVATOR ATTACHMENT FOR TRACTORS.

Application filed September 8, 1925. Serial No. 55,015.

This invention relates to new and useful improvements in farm implements and it relates more particularly to a cultivator which is attached to and made apart of a tractor.l

One of the particular features embodied in this arrangement is that the tractor and cultivator thus form a unit and enable the unit to be operated by one man.

Another important object of the invention is to provide a tractor cultivator unit so constructed that the cultivatoa1 beams carrying the plows may be shifted laterally while 'the cultivator shovels are in the ground, thus enabling the plows .to align with irregularities of the rows.

A further important feature is that each plow beam may ber adjusted individually as to depth and all the beams raised or lowered while in their adjusted positions.;

Means are also provided for holding` the plow beams or cultivatorfeetin the ground, and also the construction of the machine permits the control levers of the engine to be within easy reach for operation.V

With lthe above and other objects in view, theinvention will be better understood by reference to the following description taken in connection with the accompanying drawings forming part hereof and in which Figure 1 isa plan view of a tractor of universal type and embodying the cultivator.

Figure 2 is a side view partly in section of the cultivator and co-acting parts.

Figure 3 is a sectional detail view of a foot'pedal and connecting parts: for shifting the beams from side to side.

Figure 4 isa sectional detail view of a spring and connecting parts for holding the plows in the ground.

Figure 5 is a detail viewof means employed -to support the steering shaft and operating levers of the tractor engine.

I Figure 9 is a detail View of one of the levers and segment for lifting each beam individually, and

Figure 10 isa sectional detail view of one of the levers and segments for lifting the beams collectively.

In thedrawings wherein separate numerals are used to designate various parts, 1 denotes a tractor engine, 2 the transmission case and 3' the axles with supporting wheels 1-4. The spark, choke and gas levers are indicated at 5, 6 land 7 and the clutch lever at 8. rllhe spark, choke and gas levers are supported and are passed through avdiagonally disposed bar 9, shown in Figure 5. This bar is supported by amember 10 secured to one of the seat supporting bars 11.

The steering rod 12 is also passed through` and is supported by the member 10 and the gear shift lever 13 also traverses and is supported by the bar 9. The gasvlever 7 extends to. within easy reach of the steering wheel 14 near the seat 15 and is also supported by a member 16 secured to one of the seat rods 11. VThis arrangement places all the control levers within easy reach of the operator, particularly the gas lever 7.

,Each cultivatorbeam 17 carries cultivator shovels 18 and these beams are provided on their inner ends with cuffs 19. These cuffs as will be seen by reference to Figure 7, have spaced ends 20 for' spacer members 21 provided with set screws 22, the screws y to hold the beams in adjusted position. Spacer'members 21a'have projections 21b to stabilizerthe beams. A. rod 24 traverses the cuffs and spacer members, and the beams have free movement up and down while in adjusted position. The rod 24 is securedto spaced eye members 25 fastened to the draw bar 26. Thisdraw-bar as will be observed in Figures 1 and 2, is supported upon angle.

irons 27 arranged'in the center of the machine and bolted to the transmission case n and is also .provided with brace rods 28,V also bolted to the transmissionrcase, one'brace-V rod on eachside of the'transmission'case being Yextended underneath the 'sa-me as be lifted or lowered.

shown by dotted lines. Braces 29 also extend from the bar 2T to a partof the trame which consists ot two bars 30MB() extending from side to side of the machine. Connect ed to the traine 30 by supports 3l Iare two bars 32 ol square Aformation and rounded on their outer ends The rounded outer ends 33 ot' these shafts or bars 32 have connected thereto through the medium oi the levers cultivator beams 17, whereas a lever 35 is connectedto the medial or square portion et cach shaft by means of the set screws 3G so that by manually moving the lever 35 the shafts 32 will be oscillated and inturn raise and lower each set ot cultivator beams. Adjacent lever 35 is a segment 3T which has a rounded cere 3S through which the square bar passes. This segment has the usual plunger rod to engage its teeth to lock the lever 35 in position. By this` arrange ment the square rod may be rotated and will liftits two beams 17 clear of the ground, as will be apparent hereinafter. y

By reference to Figures 2, G and 9 it will `be observed that the round ends 33 or bar 32 carry two levers 3a and segment 40, the segment being secured by set screw to the square bar 32. Now when it is desired to adjust the plows individually, lever 3st is depressed or raised and the lever being attached to the beam by rod Lll, the beam will The spring [lf2 acts to hold the plows downward. `When properly adjusted, the two beams on each side may be both raised at once by the middle lever 35,

'since the segments zl() are rigid on shaft 82. A spring 43 assists in the raising and lower ing of the beams.

lThe means'for shifting the beams is provided for by the ioot pedals all, pivoted to the seat bars. These pedals have connected thereto a` small rod 45, one on each pedal, and leading to a cross member 46. This cross member has a forwardly extended end il? which is pivoted to an arch bar 48. This bar is y:fastened by set screws 49 to the spacers E21:l and each end has several holes 50 for adjustment. Then the right hand loot pedal is moved forward all the beams are shifted to the right, the left hand pedal shitting them to the lett. These beams are shifted along with the rod 2-l, the projection 2lb sliding` along the pin 51.

From the foregoing it will be apparent that the machine will carry out the objects set iorth in a practical manner, and provides a two row cultivatorwhich can be operated by one man. It should be understood that the tractor-cultivator is not limited to the speciic arrangement tor bringing about the operation thereof, but may be altered and modified to come within the meaning of the `following claims.
